On the topic of (not) going too far

From time to time, I find quotes that were meant to be motivating, eventhough I find that they should be handled with care.
One such occasion was when I saw the following quote by the author T. S. Eliot:

Only those who will risk going too far can possibly find out how far one can go.

It's probably true. But in times, where moderate voices seem to under an increasing pressure from people with more extreme points of view, I am afraid that what we need might not be those who are willing to go too far. I think there are enough of those. We rather need an appeal to normal, moderate people.
